Enjoying the Weather

Here in Michigan the temperature has dropped to 26-28 Degrees (F) and no snow. Maybe its just me, but my car feels faster. Engine sounds throatier and my intake is louder. I have an ECIS intake which many people think doesn't do much, but during the winter I think it makes a more noticable difference. With the 3.46 diff and intake my car is pulling harder, especially from gears 1-3. My car is a lot more fun to drive only if the snow holds up. Has anyone else noticed this?

Yes, it is true. Colder and denser air will have oxygen molecules packed closer together allow the engine to operate more efficiently and make more power. Unfortunately, it's still going to be 80 degrees here in TX today, so I won't get to enjoy Mother Nature's Ram-Air Kit just yet. Have fun with yours though.
